摘　　要：在磨削难加工材料制成或具有薄壁、大长径比、复杂曲面结构的零部件时,磨削系统颤振会直接影响零部件表面加工质量和轮廓精度,从而影响使用寿命。但是目前对磨削颤振系统产生机理,稳定性模型建立与分析的研究仍有不足。深入开展磨削加工过程中颤振稳定性研究对于提升加工质量、保障磨削系统稳定运行具有重要意义。围绕磨削颤振机理、磨削稳定性建模与求解方法和应用进行综述,首先分析磨削系统稳定性的主要影响因素,深入讨论颤振的成因和磨削系统动力学建模进展;然后,从频域、时域、实验等方面重点分析磨削稳定性模型的求解方法,比较并归纳各种求解方法的过程原理、研究现状与优缺点;最后总结稳定性分析应用方法与现状,并对磨削加工颤振稳定性研究未来的发展方向进行展望。When grinding difficult-to-machine materials or parts with thin walls,large length-to-diameter ratios,and complex curved surfaces,grinding system vibration will directly affect the surface processing quality and contour accuracy of parts,thereby affecting their service life.However,research on the mechanism of grinding vibration system generation,stability model establishment and analysis is still insufficient.The research on the stability of grinding vibration system is of great significance for improving processing quality and ensuring stable operation of the grinding system.The review focuses on the grinding chatter mechanism,modeling and solving methods of grinding stability,and its applications.Firstly,it analyzes the main influencing factors of grinding system stability,and discusses in depth the causes of vibration and the progress of dynamic modeling of the grinding system.Then,it focuses on analyzing the solving methods of grinding stability model from frequency domain,time domain,experiment and other aspects,comparing and summarizing the process principles,research status and advantages and disadvantages of various solving methods.Finally,it summarizes the application methods and status quo of stability analysis,and looks forward to the future development direction of grinding vibration stability research.
